在Ansible中,可以使用with_nested和with_together过滤器来遍历多个单独的列表。以下是一个示例:
---
- hosts: localhost
gather_facts: false
vars:
fruits:
- apple
- banana
- orange
colors:
- red
- yellow
- orange
tasks:
- name: Loop through multiple lists with with_nested
debug:
msg: "{{ item.0 }} is {{ item.1 }}"
with_nested:
- "{{ fruits }}"
- "{{ colors }}"
- name: Loop through multiple lists with with_together
debug:
msg: "{{ item.0 }} is {{ item.1 }}"
with_together:
- "{{ fruits }}"
- "{{ colors }}"
在上面的示例中,我们有两个列表 fruits
和 colors
。首先,我们使用 with_nested
迭代两个列表,并将它们作为 item.0
和 item.1
使用。然后,我们使用 debug
模块打印出每个元素的值。
另外,我们还可以使用 with_together
过滤器来同时迭代两个列表。在这种情况下,我们可以使用 item.0
和 item.1
来访问每个列表的元素。
运行上述示例代码,将会输出以下结果:
TASK [Loop through multiple lists with with_nested] ***************************
ok: [localhost] => (item=[u'apple', u'red']) => {
"msg": "apple is red"
}
ok: [localhost] => (item=[u'apple', u'yellow']) => {
"msg": "apple is yellow"
}
ok: [localhost] => (item=[u'apple', u'orange']) => {
"msg": "apple is orange"
}
ok: [localhost] => (item=[u'banana', u'red']) => {
"msg": "banana is red"
}
ok: [localhost] => (item=[u'banana', u'yellow']) => {
"msg": "banana is yellow"
}
ok: [localhost] => (item=[u'banana', u'orange']) => {
"msg": "banana is orange"
}
ok: [localhost] => (item=[u'orange', u'red']) => {
"msg": "orange is red"
}
ok: [localhost] => (item=[u'orange', u'yellow']) => {
"msg": "orange is yellow"
}
ok: [localhost] => (item=[u'orange', u'orange']) => {
"msg": "orange is orange"
}
TASK [Loop through multiple lists with with_together] *************************
ok: [localhost] => (item=[u'apple', u'red']) => {
"msg": "apple is red"
}
ok: [localhost] => (item=[u'banana', u'yellow']) => {
"msg": "banana is yellow"
}
ok: [localhost] => (item=[u'orange', u'orange']) => {
"msg": "orange is orange"
}
如上所示,我们成功地使用 with_nested
和 with_together
迭代了两个单独的列表,并打印出了每个元素的值。
